I'm a Cairo-based Flutter Developer specializing in Clean Architecture, Riverpod, and end-to-end CI/CD. I've shipped production apps for real merchants, thousands of users, and live stores — not just side projects.

Currently at Tuwaiq Pay — a live fintech platform where I own the full mobile stack: from NearPay NFC payments and biometric auth to CI/CD pipelines and App Store releases. Previously mentored 50+ developers at Google Developer Student Clubs, leading real-world Flutter projects from scratch to deployment.

  • Clean Architecture + Riverpod / BLoC expert
  • Architecture → CI/CD → store release
  • NearPay SDK & payment integrations
  • Arabic / English bilingual apps
  • Agile / Scrum team experience
